Stargate: War Begins is a full conversion for the awesome tactical fleet simulator Nexus: The Jupiter Incident. We intend to recreate the feeling of the hit Sci-fi Tv shows Stargate SG-1, Stargate Atlantis and Stargate Universe. Our goals are to implement all of the ships seen in the series, and the original Stargate movie, and to release a full single player campaign, with configurable ships, and all the oppurtunities Nexus can provide.

Okay, if they're cargo vessels, then they should be lightly armed, yes? Unless they can use their cargo space as extra ammunition space for the Wraith equivalent of missiles or torpedos, which would be interesting to see.
